Benefits of technology
The patent describes a technique for analyzing data in a communication network using inferential statistics, which eliminates the need for network monitoring. This reduces the amount of data that needs to be collected and processed, which saves time, money, and network resources. The technique is particularly useful in a specific scenario called "Circuit Switched FallBack" in a LTE network.
Problems solved by technology
However, correlating information and data is generally complex and also expensive in terms of monitoring resources.

Embodiment Construction
[0025]Long Term Evolution (LTE) networks provide high throughput, lower latency, and superior end-user experiences. Accordingly, LTE networks and LTE protocols have been largely embraced by mobile operators and cell phone manufacturers as the next generation technology. However, at present, data remains the only service supported. That is, voice services typically remain within traditional Circuit Switched (CS) voice networks until both data and voice services are be shifted and supported by LTE infrastructure (e.g., using Voice over IP on LTE or VoLTE protocols). In the interim, service providers, hardware manufactures, and the like employ various solutions to address the dichotomy between the CS domain and LTE infrastructure (i.e., a packet switched (PS) infrastructure).
[0026]One of these possible interim solutions sponsored by the 3GPP community, use Circuit-Switched FallBack (CSFB) techniques when, for example, a user's mobile device is operating in LTE (PS data) mode. In this L...

Network monitoring devices and network monitoring techniques are disclosed and use inferential statistical approaches to determine one or more Key Performance Indicators, particularly for Circuit Switched FallBack (CSFB) scenarios. For example, the network monitoring node monitors a plurality of ciphered or clear text messages for a network interface in a communication network, determines a Mobile Terminating (MT) count for MT calls and a Mobile Originating (MO) count for User Equipment (UE) from at least one message of the plurality of messages and defines an inferred MT ratio based on the MT count and the MO count for a total number of messages. The network monitoring device further applies the inferred MT ratio to a CSFB idle mode count for UE and / or a CSFB active mode count for UE to yield an estimated total number of CSFB idle mode successes and an estimated total number of CSFB active mode successes, respectively.
Description
BACKGROUND[0001]1. Field of the Invention[0002]The present disclosure relates to network monitoring in communication networks, and more particularly, to determining Key Performance indicators (KPIs) using inferential statistics.[0003]2. Description of the Related Art[0004]One typical need for Network Operators is measuring network performances, troubleshooting network nodes, interfaces, and the like, and controlling the services' behavior. There are several use cases regarding these aspects as the deployment of new network technology in field, the control of new services or simply the performance management of the network to prevent instability, overload and other issues on the network.[0005]In order to deal with these challenges, Network Operators often use external monitoring systems. These monitoring systems are typically connected to the network in non-intrusive mode, sniffing and processing the traffic data and providing feedbacks to the Network Operators. This output can be pr...
